A low-temperature refrigerant liquid flowing from the refrigerant tank (T) through the tank-side refrigerant pipe (20) and a high-temperature refrigerant liquid flowing from the condenser (3) through the condenser-side refrigerant pipe (16). Merge at the U-seal part (16A) and the refrigerant liquid at 20-30 ° C evaporator (4)
Flows to Therefore, it is possible to prevent the refrigerant liquid in the condenser-side refrigerant pipe (16) from being flushed from the evaporator (4) side. As a result, the refrigerant liquid always exists in the condenser-side refrigerant pipe (16). In addition, the sealing between the condenser (3) and the evaporator (4) can be reliably performed. In addition, since the seal between the condenser (3) and the evaporator (4) is securely performed, the pressure difference between the condenser (3) and the evaporator (4) is reduced, and the evaporator (4) is removed.

できる。Further, since the pressure equalizing pipe (24) is provided between the refrigerant tank (T) and the gas phase portion of the evaporator (4), the pressure between the refrigerant tank (T) and the evaporator (4) is approximately equal. As a result, the refrigerant liquid can flow smoothly from the refrigerant tank (T) to the evaporator (4). Further, the non-condensable gas generated in the refrigerant tank (T) flows to the evaporator (4) through the pressure equalizing pipe (24), so that it is possible to prevent the non-condensable gas from remaining in the refrigerant tank (T). .

In addition, since the low-temperature refrigerant liquid flows from the refrigerant tank (T) to the condenser-side refrigerant pipe (16) and merges with the high-temperature refrigerant liquid flowing from the condenser (3), the temperature of the refrigerant liquid decreases. Can always be sent to the evaporator (4).
